And of course that doesn't include any other side mini's or event mini's or Ultimate mini's (like ULTIMATE X4 or ULTIMATE WOLVERINE VS. HULK).
To be fair, though, ASTONISHING X-MEN doesn't come out frequently and given how they're announcing it as "bimonthly" for 2006, means that at most it'll have 6 issues this year. In 2005 they only shipped 5 issues, and late ones at that. Methinks while the title sells very well, Marvel knows better than to plan ASTONISHING as the flagship X-book, as it is rarely out.
And before someone mentions it, yes, DC does the same thing with Superman and Batman. And it's not right when they do it, either. There, happy? Covered that excuse? Good. In the real world, "he does it too!" stops working to accurately defend your position outside of the first grade schoolyard. Shame many adults haven't realized this.
The irony is that X-23, not Wolverine, had the power to up the sales of a book by no other virtue than a guest appearence last year. And I don't care for her much either.
